'2 Claims. (Cl. 74-37) 'Ifhis invention relates to winding machinesthese machines W are typical of the kind with variously employed forexample in the textile winding units in multiple serially arranged inindustry to wind yarns into conical or cylindric straight rows alongtheir opposite sides, the packages (ordinarilyreferred to as cones orbobbin B of each such winding unit serving cheeses) of a convenient sizesuitable for yarn to a reciprocating guide G incident to 60 use inknitting machines and the like, to wind formation of a yarn package orcone C in a yarns on spools, etc.; and has more particular manner wellunderstood in this art. reference to that type of winding machines Totransport the operatives back and forth with winding units in multiplearranged serially within the aisles A past the winding units along l0 instraight rows along opposite sides.

In the main, my invention is directed toward to Figs. II-IV it will beobserved that the caralleviating the unsatisfactory condition to whichriage 10 is equipped with a clutch means 20 attention has been directed,that is to say, I comprising a pair of grip members 21, 22 that aim` tominimize fatigue incident to running are independently fulcrumed to afixed drop 25 spinning machines of the kind referred to.

Still referring to Figs.

With the clutchmeans in the position of trations, I have depicted in Fig. I a group ofFigs. II and III, the carriage 10 will obviously winding machines Warranged side by side, afbe moved to the left as indicated by the arrow,ter common practice in gang grouping, with shown on the first mentionedfigure, until the traversing aisles A between them. As shown, tripfinger 31 encounters the stop 32 which oc- I 'ljo curs at just about thetime when said carriage nears the limit of its movement in the indicateddirection. As a consequence of the encounter of the trip ringer 3l withthe stop 32, the clutch 20 is actuated and the upper toothed member 2lwithdrawn from the top chain run, while the lower toothed member 22 isengaged with the bottom chain run, the new position of the parts beingmaintained through swinging of the counterweighted lever 30 to theopposite side of the vertical dead center in an obvious manner. Thecarriage 10 is thereupon propelled in the reverse direction until thetrip nger 31 encounters the stop 33, with consequent restoration o theclutch 20 to the illustrated position at the end of 'the travel to theright, in preparation for the succeeding return movement.. The carriage`10 is thus moved continuously and automatically back and forth in theaisle A.

To enable stoppage at any point along the lin of travel I form the frame28 with a foot treadle 34 which is conveniently accessible to theoperative when seated on a swivel stool 35 centrally of the carriage 10.Depression of the treadle 34 obviously causes the frame 2S to be swungon its axis 29, thereby to bring the clutch members 2l, 22 to a neutralposition so that neither of them engages the propelling sprocket chain13, as shown in Fig. IV, with consequent cessation in the travel of thecarriage 10.

At each side, the carriage 10 is equipped with a magazine or holder 36for lled or loaded bobbins B which are withdrawable successively throughan outlet at 37; as well as with a receiver 38 for the empty bobbins,said receiver' having an inclined bottom, as shown in Fig. III, forcapacity to discharge endwise through a door 39. This door 39 is pivotedto the receiver 38 so as to swing upward, and has an actuating arm 40adapted to be engaged by a stop 41 at the end of the carriage travelwith resultant swinging of said door to open position and discharge ofthe collected empty bobbins B into a waiting receptacle 42 adjacent thestop 41. The described construction and operation of course holds forthe conveying equipment for an operative in each of the aisles A.

rIhe several propelling chains 13 may be driven from a common source ofpower, and to this end, the guide wheels 15 are shown as mounted on aline shaft 45 which is coordinated, by a belt or chain 46, with acountershaft 47 arranged to be driven in turn, through speed reductiongearing 48, by an electric motor 49. In practice. the speedpredetermined for the propelling chains 13 is such that the operativesare afforded ample time to replace empty bobbins B and give whateverother attention may be required at each of the winding units incident topassage of the carriage 10 back and forth between neighboring machinesW, the new bobbins B being within easy reach by virtue of support of theholders or magazines 36 at arm level, while the replaced empty bobbins Bmay be readily dropped into the receivers 38 for automatic dischargelater under gravity influence into the collecting boxes 42 at the endsof the machines W in the manner previously explained.

While I have herein shown and described my invention in connection withyarn winding machines W, I do not wish to be limited to this particularfield alone since it may obviously be used with attainment ofcorresponding advantage in connection with other machines for winding orspooling materials in strand form even including Wire.

Having thus described my invention, I claim:

1. In winding machines with longitudinally arranged series of windingunits, including a wheeled carriage to support an operative, and a railtrack for the carriage extending alongside the winding machine, aconstantly-moving endless chain lengthwise intermediate the track rails,and means comprising opposingly-active independently-fulcrumed gripmembers, subject to counterbalancing-influence, supported by thecarriage for alternate coupling engagement with the respective flightsof the endless chain to automatically propel said carriage along thetrack and convey the operative back and forth past the winding units.

2. In winding machines With longitudinally arranged series of windingunits, including a wheeled carriage to support an operative, and a railtrack for the carriage extending alongside the winding machine, aconstantly-moving endless chain progressing in a vertical planelengthwise medially intermediate the track rails, means comprisingopposingly-toothed independently-fulcrumed members, subject tocounterbalancing-innuence, supported by a drop-bracket from the carriagefor alternate coupling engagement with the upper and lower flights ofthe endless chain to automatically propel said carriage along the trackand convey the operative back and forth past the winding units, andmanually-operable means whereby the carriage may be stopped at any pointalong its path of travel.
